Hiroshi Nakamura (@nahi), a frequent attendee of trbmeetup, and committer both of CRuby and JRuby, will present at our next event. He will talk about how he got involved with the both projects, the difference in development style between the two projects, and how you can join too. Additionally, he will cover more concrete issues he is working on, such as the gemification of the Ruby standard library, and concurrent require issues.
